Avast finds that file " C:\windows\assembly\GAC_32\Desktop.ini " is infected by Win32:Malware-gen.[/font][/font][/font](it always appears duplicated in the scan log). If I try anything else but excluding the infected files it avast show a message of "access error (5)".But even if I exclude them and make a scan at boot mode, this infected file is found again exactly the same way after some time.

I already used Malwarebytes to scan and remove malwares (many were found). But even so the problem is not solved.

IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

Double click on ComboFix.exe & follow the prompts.

Accept the disclaimer and allow to update if it asks

When finished, it shall produce a log for you.

Please include the C:\ComboFix.txt in your next reply.[/b]

Notes:1. Do not mouse-click Combofix's window while it is running. That may cause it to stall.2. Do not "re-run" Combofix. If you have a problem, reply back for further instructions.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

attached, the logs from OTL and then from ComboFix (the one at the end of the scan and fix and another which was created after the computer was restarted).Combofix pointed that MacAfee was enabled, but I have already uninstalled this antivirus after I installed Avast. I even looked for any file with Macafee name and nothing was found. it is also not on the list of files at Control Panel. so, I guess, no need for worries.

Oh no!I made a complete scan with Avast again. and the same way C:\Windows\assemply\GAC_32\Desktop appears two times infected by Win32:Malware-gen_and now a THIRD infected file was shown, which is C:\_OTL\MovedFiles\09252011_194357\C_windows\assembly\GAC_32\Desktop.ini.

This third was easily isolated by avast. the other I can only exclude like before, but not isolate.

The one in the OTL files was one that we had allready moved - lets give combofix a shot at it

1. Close any open browsers.2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix. 3. Open notepad and copy/paste the text in the quotebox below into it:

Quote

File::C:\windows\assembly\GAC_32\Desktop.ini.

Save this as CFScript.txt, in the same location as ComboFix.exe

Refering to the picture above, drag CFScript into ComboFix.exeWhen finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Yesterday. right after my reply starting with "oh no!" avast requested to complete the scan by restarting the computer (to run a scan before windows is initialized).During the scan the battery went down and the laptop was not connected properly to energy source. So it might have shut down during the scan (not sure. I was sleeping).

After I initialize it again there was a process of checking wheter there was any damage.After opening windows again, two strange things happened.

The most relevant might be that there are now two files named desktop.ini at my desktop (and Combofix disappeared from the desktop).

Another thing is that the icons of some folders are displayed with a lock. (Folders C:\Documents and Settings C:\MSOCache C:\System Volume Information and E:\System Volume Information).

But the computer seems to be working normally. I ran another scan with avast, the same viruses as usual were found and isolated (or excluded in the case of desktop.ini at GAC_32). And then I followed your instructions to make this new log which is attached to the message.

This is normal as they are hidden files that were revealed during the cleaning process, we will hide them again on completion

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems

Now the best part of the day ----- Your log now appears clean :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset System Restore points:

Run OTL

Under the Custom Scans/Fixes box at the bottom, paste in the following

Quote

:Commands[resethosts][purity][emptytemp][EMPTYFLASH][Reboot]

Then click the Run Fix button at the top

Let the program run unhindered, reboot the PC when it is done

Remove ComboFix

Hold down the Windows key + R on your keyboard. This will display the Run dialogue box

In the Run box, type in ComboFix /Uninstall(Notice the space between the "x" and "/") then click OK

Follow the prompts on the screen

A message should appear confirming that ComboFix was uninstalled

Run OTL and hit the cleanup button. It will remove all the programmes we have used plus itself.

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

Click Start.

Open My Computer.

Select the Tools menu and click Folder Options.

Select the View Tab.

Under the Hidden files and folders heading select Do not show hidden files and folders.

Click Yes to confirm.

Click OK.
